Patent CA-2338983-A1 (CA)
Inventor: NUNBERG JACK H
IPC: C07K19/00
Filed: 1999-08-03
Abstract: The invention relates to the generation of Fusion-Related Molecular Structures (FRMS) which comprise one or more transitional fusion-related determinants.  Highly effective vaccines may be constructed which present the fusion-related determinants to the immune system that engender unique antibodies capable of potently neutralizing a broad range of primary isolates, from worldwide locations and from different phylogenetic viral clades. The present invention provides methods for formation, isolation and purification of the FRMS as well as the use of such FRMS in a variety of compositions and methods, including, for example, as vaccine immunogens, diagnostics, and therapeutics. The present invention concerns FRMS capable of eliciting neutralizing antibodies to viral pathogens and primary isolates of a virus. Antibodies raised to the FRMS can be used to study the molecular pathway toward fusion of the virus and host cell and to identify points of a possible antibody-mediated blockade to that pathway. The invention also relates to the use of antibodies of the invention for anti-viral agents, blood product additives, contraceptive additives passive immunization in post-exposure treatments or fetus immunization.

Title: All gear infinitely variable transmission
Inventor: KERR JOHN HUGH
IPC: F16H29/00
Filed: 1999-10-15
Abstract: An infinitely-variable transmission consists of a rotational input member, a rotational output member, first and second non-circular driving gears coupled to one of the rotational members, and a plurality of variable velocity-ratio gear assemblies disposed about the one rotational member. Each gear assembly comprises an intermediate shaft including first and second non-circular driven gears respectively meshing with the first and second non-circular driving gears. Each gear assembly also comprises a multi-directional coupling associated with the pair of first driven/driving gears and the pair of second driven/driving gears, and an actuator associated with the coupling for coupling the first and second variable-ratio gear pairs to the rotational members.  Preferably, the variable-ratio gear pairs for each gear assembly are coupled to the rotational members over an angular duration when the velocity ratios of both the variable-ratio gear pairs of the respective gear assembly are changing linearly so as to provide a uniform velocity ratio over that angular duration. Further, preferably the occurrences of these angular durations for each of the gear assemblies overlap or are at least coterminous so as to provide a continuously uniform velocity ratio between the rotational members. The transmission also includes a phase angle variator associated with the variable-ratio gear pairs for varying the rotational angular displacement between the first gear pairs and the second gear pairs of each gear assembly so as to vary the velocity ratio of the transmission as needed.

Title: Field emission charge controlled mirror (fea-ccm)
Inventor: ROBINSON WILLIAM P
IPC: B81B3/00
Filed: 1999-10-14
Abstract: A bright, high contrast, compact, large area, high-resolution light modulato r (50) uses a field emitter array (FEA) (52) to address a charge controlled mirror (CCM) (54). The FEA deposits a charge pattern onto the CCM, which in turn produces electrostatic forces that deflect the micromirrors (58) in accordance with the amount of accumulated charge. The CCM that is used in combination with the FEA can be configured in many different ways to impleme nt different actuation modes, e.g. attractive, repulsive, grid-actuated or membrane-actuated and different charge control modes, e.g. RC decay, RC sustain and charge control.

Title: Methods
Inventor: COUTELLE CHARLES
IPC: C12N15/79
Filed: 2001-10-04
Abstract: The present invention relates to a method for the production of a minicircle.  In the method of the present invention, a parent plasmid is provided which has a nucleic sequence flanked by recombination sites. This parent plasmid is exposed to an enzyme which causes recombination at the recombination sites, thereby to form a (i) minicircle comprising the nucleic acid sequence and (ii) a miniplasmid comprising the remainder of the parent plasmid. One recombination site is modified at the 5' end such that its reaction with the enzyme is less efficient than the wild type site, and the other recombination site is modified at the 3' end such that its reaction with the enzyme is less efficient than the wild type site, both modified sites being located in the minicircle after recombination. This favours the formation of minicircle.
